Problems solved by technology

[0003] Modern pig raising is mainly based on concentrated feed, which lacks sufficient crude fiber and green feed. In order to improve feed digestibility, feed raw materials are often crushed too finely. Constipation occurs when feces accumulate in the colon and rectum, and it is easy to cause constipation if the feed is changed suddenly
In addition, slight mi

Abstract

A pregnant sow feed for improving sow constipation and increasing litter size specifically comprises the raw materials, by weight, 15-40 parts of corn, 8-20 parts of soybean meal, 5-35 parts of nakedbarley, 5-20 parts of wheat bran, 2-10 parts of inulin, 0.05-0.4 part of lysine hydrochloride, 0.1-1 part of valine, 0.05-0.3 part of threonine, 0.2-1.5 parts of calcium hydrophosphate, 0.2-1.5 partsof stone powder, 0.1-0.5 part of salt and 1 part of premix. The invention provides a preparation method and application of the pregnant sow feed capable of improving the sow constipation and increasing the litter size. According to the pregnant sow feed, the growth and maintenance requirements of pregnant sows are guaranteed, meanwhile, the body condition of the sows can be controlled, the constipation of the sows can be remarkably improved, and the litter size is improved.

Description

technical field [0001] The invention belongs to the technical field of animal feed, and in particular relates to a feed for pregnant sows which can improve sow constipation and increase litter size, a preparation method and application thereof. Background technique [0002] Pregnancy is a special physiological stage for breeding sows. In order to maintain pregnancy, the sow will continue to secrete progesterone, which can slow down the contraction of the smooth muscle of the digestive tract, and the growing fetus will squeeze the gastrointestinal tract. Factors will greatly weaken the intestinal peristalsis of sows, resulting in prolonged retention time of chyme in the gastrointestinal tract and reduced defecation frequency; at the same time, sows are in the vigorous stage of "pregnancy anabolism", and the digestion and absorption of food in the gastrointestinal tract The utilization capacity of pregnant sows is much higher than that of any other stage, especially the strong...
